The study, published in the latest issue of the journal Current Biology, found that fish grew larger in small traditionally managed reserves, rather than in larger national parks and most co-managed reserves run by several partner organizations. The authors also found that traditionally managed reserves did not permanently close fishing around reefs, a technique often touted by managers as the best way to safeguard fish stocks. Instead communities occasionally opened their reserves to obtain food for feasts – an important incentive to ensure that temporary closures were enforced.
"This study clearly shows that communities with a direct stake in preserving healthy fisheries around reefs can often serve as the best managers and police to protect these areas from overfishing," said WCS biologist Dr. Tim McClanahan, the study's lead author. "Governments wishing to establish marine protected areas can learn a valuable lesson that communities must see some benefit of closures to ensure their participation and adherence to the rules."
The authors looked at a total of four national parks, four-co-managed reserves and three traditional reserves in Indonesia and Papua New Guinea, finding that traditional reserves were often managed to meet community needs, not strict conservation goals established by outsiders. These reserves also tended to be located in remote areas with small human populations, with limited influence by outsiders and markets. The one co-managed reserve that enjoyed similar results found in traditional reserves was established after careful consultation with the community along with considerable donor support.
On the basis of their findings, the authors propose that while large, permanent marine protected areas may provide the best protection for species that are at particular risk from overfishing, a combination of such large marine protected areas and traditionally managed systems may represent the best overall solution for meeting conservation and community goals and reversing the degradation of reef ecosystems. Other authors of the study include Michael J. Marnane of the Wildlife Conservation Society; Joshua E. Cinner of the Centre of Excellence for Coral Reef Studies, James Cook University in Townsville, Australia; and William Kiene of Fagatele Bay National Marine Sanctuary in Pago Pago, American Samoa.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
